SPECIFICATION forming part of Letters Patent No. 363,647, dated May' 24,1887.

Application filed March 19, 1887. Serial No. 231,600. (No model.)

To all whom it may concern-f Be it known that I, JOSEPH H. KNAU'S, acitizen of the United States, residing at Fayette, in the county ofHoward and State of M issouri, have invented certain new and usefulImprovements in Attachments for Drawers, of which the following is aspecification, reference being had to the accompanying drawings, formingpart thereof, in whieh- Figure l is a plan view of the attachment, thedrawer and the casing in which it moves being shown in dotted lines.Fig. 2 is a perspective view from the rear of the case, the drawer beingpartly withdrawn and the top of the case being removed. Fig. 3 is adiagram showing a modification.

The object of my invention is to provide an equalizing attachment fordrawers, whereby the binding of the drawer in moving it in and out of:its easing will be prevented and the friction incident theretoobviated.

The invention will be first described, and then specifically pointed outin the claims.

A represents the casing, which may be in the form of a bureau or otherarticle, having an opening, into and out of which the drawer B mayslide. The back of the easing is apertured to receive the two horizontalpulleys O C, mounted in U-shaped brackets D D, provided with aperturedears d d, which are secured to the rear side of the easing A at oppositesides of the apertures by means of screws d d. The front of the easingis provided with horizontal pulleys E E in the plane of the pulleys C C.The pulleys E E are journaled in brackets E E, secured to the under sideof the cross-piece A at the top of the draweropening by means of screwspassing through the apcrtured ears c e, projecting from the ends of` thesaid brackets. Around these four pulleys passes an endlessiiexible'strand, F, which is crossed at f, thus forming the parallelends f f and the crossed diagonal portions f 2 f 2. To each of the endsf f is secured an angular attaching-arm, G, the horizontal branch g ofwhich has at its opposite sides one or more projections, g', which arebent over the strand to secure the arm thereon. The vertical branches g2of the arms G project downward I and into the open spaces H behind thecleats o H, secured, preferably, to the inner face of the back of thedrawer B at or near its upper edge. rIlhe arms G may be readily detachedfrom the cleats by simply moving their vertical branches `(/lsidewise,when the drawer may be removed 5 5 from its easing.

By this construction it will be seen that the force applied in openingand closing the drawer will be equalized--that is, applied equally toboth sides-so that the drawer will move only in a straight line, andsidewise or jerky movement and consequent binding be prevented. Thelower ends of the branches g2 are bent outward slightly, in order thatthey may be readily grasped when it is desired to disconneet the arms Gfrom the drawer. In Fig. 3 the same arrangement of the pulleys andconnecting-arms is employed; but the endless strand G is doubled andpassed around a rear pulley, thence to and around the forward pnl- 7oleys, and back to and around the other rear pulley.

The strand may be formed of cord, wire, or chain, as desired, and anysuitable form of pulley may be used. manently connected at its sides tothe rear upper corners of the drawer, if found desirable; but I prefer areadily-detachable connection.

Having thus described my invention, what I 8O claim as new, and desireto secure by Letters Patent, is-

l. llhe combination, with the casing and the drawer, and pulleys at thefront and rear of the casing at opposite sides of the draweropening, ofthe endless strand passing around the said pulleys and connected to therear end of the drawer at or near its opposite ends, substantially asset forth.

2. The combination, with the easing and its 9o drawer, ofthe pulleys atthe front and rear of the casing, and the endless crossed strand passingaround said pulleys and connected at its sides to the drawer,substantially as set forth.

3. lIhe combination, with the casing and its v drawer, of the pulleys atthe front and rear of the easing at opposite sides of the draweropening,andthe endless strand passin around The strand may be per- 7 5,`

said pul1eys,as described, and removably connected at its sides to thedrawer, substantially as set forth.

4. The eombinatomwith the casing and its 5 drawer having cleats, ot thepulleys at the front and rear of the casing at opposite sides 0f Vitsdrawer-opening, and the endless strand passing around the pulleys andhaving the depending arms entering the spaces in rear of I0 the cleats,substantially as set forth.

5. In a drawer-equalizing attachment, the angular connecting-arm formedwith clamping projections on its horizontal arms, whereby it may bereadily secured to a strand, substantially as set forth.
